Patent GB-886497-A (GB)
Title: Improvements in or relating to transistor circuits
IPC: G11C11/406
Filed: 1959-02-16
Abstract: 886,497. Transistor pulse circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 16, 1959 [Feb. 24, 1958], No. 5331/59. Class 40(6). In a transistor pulse circuit a capacitor 10, the emitter-collector path of a transistor 18 and a load are connected in series across a unidirectional voltage source, so that, when the capacitor 10 is discharged, the application of a pulse of suitable polarity to the base of transistor 18 causes a pulse of current to flow thereby charging the capacitor and producing an output signal across the load, but the application of a subsequent similar pulse to the base of the transistor while the capacitor 10 remains charged does not cause any current to flow in the series circuit. In the circuit shown the output signal is developed in the secondary winding 32 of a load transformer having its primary winding in series with the transistor 18. A further transistor 36 may be connected in parallel with the capacitor 10, the application of a re-set pulse to its base electrode serving to discharge the capacitor if charged. In the application of the circuit for delivering an output in the absence of inputs X, Y but the presence of an input C, two further transistors 60, 54 to which the X, Y inputs are applied are connected as shown in Fig. 2. Transformers 56 and 62 deliver pulses which are returned to the sending equipment for checking purposes. The timing of the X,Y pulses precedes that of the C pulses; only if the C pulse is not immediately preceded by an X or Y pulse will an output be obtained from the secondary winding 32.

Filed: 1950-03-03
Abstract: 677,929. Delivering liquids or powdered materials in measured quantities. BRITISH UNITED SHOE MACHINERY CO., Ltd., ELLIOTT, H. E., SMITH, F. R., and PRATT, J. W. March 2, 1951 [March 3, 1950], No. 5404/50. Class 106(v) [Also in Group II] In a machine for mixing potato powder and water, measured volumes of these materials are delivered simultaneously under gravity from a powder hopper 3 and a water tank 5 into the mixing vessel. The measuring devices are controlled by a common operating lever, Fig. 1 (not shown) which is coupled by means of a link 31, and pawl and ratchet mechanism 21, 23, 27 to a four-compartment pocket wheel 13 at the bottom of the powder hopper 3, the arrangement being such as to rotate the pocket wheel through one quarter of a revolution when the operating lever is depressed. The operating lever is coupled also to a rod 55 which extends axially through a measuring cylinder 45 within the water tank 5. Collars 57, 63, are secured on the rod 55 and between the collars, slidably mounted upon the rod, are valve members 59, 65, which are urged in opposite directions by a compressing spring 71. When the operating lever is moved to deliver a charge of materials to the mixing vessel, the rod 55 is lifted so that the valve member 59 closes an inlet 50 to the cylinder 45 and the valve member 65 opens a discharge outlet 69. When the operating lever is allowed to return to its original position, the rod 55 moves downwardly, thereby first closing the outlet 69 and then opening the inlet 50 so that water flows from the tank 5 to fill the cylinder 45 ready for the next operation of the lever. A vent 61 from the cylinder 45 extends to above the level of the water in the tank 5.

Abstract: 750,844. Turning bobbins. AKTIEBOLAGET INDUSTRIKOMPANIET. Feb. 26, 1954, No. 5713/54. Class 83 (3). A method of turning bobbins; spools, &c. comprises setting up blanks on a rotatable carrier, each blank rotating about its own axis while fed successively past one or more turning tools, the blanks being turned into the desired shape while the carrier is rotating and the tools being moved along the carrier and returned to the original position on completion of the operation. The blanks R, Figs. 1 and 3, are carried between drivers 6 and tailstock spindles 8 at the ends of U-shaped arms 3 extending from the hub 2 of a continuously - driven wheel - like member carried by a shaft 1 rotated by worm gearing 14, 15, Fig. 2, from a shaft 16. The drivers 6 are rotated for the turning operations by a continuous belt or chain 11 passing over pulleys &c. 4 secured to the drivel spindles, and the drive is from an electric motor 12, Fig. 1, on the base of the machine. The blanks are introduced at point A, Fig. 1, and a lever 23, Figs. 2 and 3, is operated by cam mechanism 20 at this position to press the tailstock spindle 8 against the blank and over the driver 6. The tools 30a, 31a, &c., Fig. 1, are carried on rests 30, 31, &c., arranged circumferentially around the rotating work-carrier on an arcuate support 24 to which 'they are pivotally connected. The support 24, Fig. 2, is guided for movement on a series of fixed blocks 25 and is rocked to follow up the movement of the work and make a quick return by a cam slot 27 which moves a follower on the end of a rod 26 connected to the support. The tools are additionally rocked to feed them towards the work by connecting members 35, 36, Fig. 1, moved by a peripheral cam 28 which carries the cam track 27 and rotates on a shaft 29. In a modified arrangement of tool-carriers an arcuate support 112, Fig. 10, is used, but the tool rests 115, Fig. 7, move radially thereon. Feed is effected from overhead eccentric spindles 101 rotated by gear-wheels 109, Fig. 10, which engage a fixed rack 111 as the arcuate support moves. Links 104 connect the spindles 101 to eccentric pins on the ends of adjustable spindles 107 carried by the tool rests 115; the rests are thus initially adjustable for operating on different sizes of bobbins.

Title: Improvements in electrical oscillators comprising thermionic valves
IPC: H03B5/10
Filed: 1940-04-01
Abstract: 538,674. Valve generating circuits. GENERAL ELECTRIC CO., Ltd., and RIVLIN, R. S. April 1, 1940, No. 5829. [Class 40 (v)] A plurality of fundamental frequencies is generated by a single valve having a number of stable reaction circuits each containing a tuned element or circuit and some form of amplitudelimiting element such as a resistance which varies with the current, so that the current through the reaction circuit cannot exceed a finite maximum. The reaction circuits are so arranged that oscillations characteristic of one circuit are prevented from entering another, and the amplitudes of the oscillations are such that the valve operates always on the linear part of its characteristic. The output circuit of the valve may be coupled to its input circuit by two or more reaction circuits each containing two crystals 16, 17 and a resistance bridge 8, 9, 10, 11, of which one member 11 varies rapidly with the current through it, as in Specification 510,379. In a modified arrangement the reaction circuit includes two crystals in series, with a Thyrite resistance connected in parallel across the circuit, so that as the amplitude of the oscillations increases the proportion shunted increases and thus limits the amplitude. Specifications 335,507, [Class 40 (v)], and 533,736 also are referred to.

Title: Improvements in or relating to electric resistance heating filaments
IPC: C25D13/02
Filed: 1956-02-27
Abstract: 814,404. Electric resistance heating filaments. TELEFUNKEN G.m.b.H. Feb. 27, 1956 [Feb. 26, 1955], No. 5971/56. Class 39(3) [Also in Group XXXVI] A heating filament, especially for an indirectly heated cathode of an electron discharge device has on its surface an insulating layer composed of a substance containing gallium, and preferably composed of aluminium oxide with 0.05 to 3 per cent of gallium oxide. The aluminium oxide crystals may be coated with a thin layer of gallium hydroxide, formed by precipitating gallium hydroxide or a double hydroxide of gallium and aluminium on the aluminium oxide crystals. The coated crystals are applied e.g. electrophoretically to the filament and heated to incandescence to form gallium oxide, which increases the cohesion between the crystals. Thus one part of finely ground aluminium oxide is mixed with two parts of an aqueous solution containing 0.02 parts of an acidic gallium salt e.g. gallium nitrate or a basic gallium compound e.g. sodium gallate. If an acidic gallium salt is used, an ammonium radical is used as precipitation medium, or the suspension is boiled with a substance absorbing free hydrogen ions e.g. carbonates acetates or thiosulphates. If a basic gallium compound is used, gallium hydroxide is precipitated by introducing carbon dioxide until the pH value is 8. The coated crystals precipitated are filtered, washed with water, then formed into a suspension with methanol, and deposited on the filament electrophoretically.

Title: Improvements in or relating to presses
IPC: B30B1/26
Filed: 1955-03-01
Abstract: 769,359. Operating mechanical presses. SCHULER AKT.-GES., L. March 1, 1955 [March 19, 1954], No. 6067/55. Class 87(2). The power unit for driving the ram of a press is coupled through a flywheel to a change speed gear providing at least one fast speed for the idling stroke and one slow speed for the working stroke of the press ram, the driven shaft of the change speed gear being connectable to the final drive for the press ram through a clutch or clutches controlled by means operable to select the required speed for the press ram operation. As shown in Fig. 1 the two cranks 27, 28 of a double press are driven through gearing including a wheel 19 which meshes with the wheel 16 of control gear 17 mounted on top of the press, the driving motor 1 being similarly mounted and driving a flywheel 2 fixed to the layshaft 3, Fig. 2. The control gear includes two clutches 9, 10 and a brake 15. The housings of the clutches 9, 10 are fixed to gear wheels 8, 7 respectively and to the inside of each housing is fixed a group of clutch plates. In the spaces between these plates are corresponding groups of clutch plates fixed to collars 11, 12 splined to the driven shaft 6 of the control gear. A brake 15, of similar construction, has its housing fixed to a bearing 31. When the ram of the press is raised, i.e. when the crank is in position a, a compressed air cylinder 13 is operated by electromechanical means to cause an extension of its piston rod which projects into an axial bore in the shaft 6 to move a sleeve 29 (connected to the rod through transverse slots in the shaft in a direction to bring the plates of the clutch 9 into engagement. The same electromechanical connection causes the piston of a compressed air cylinder mounted in the housing of the brake 15 to disengage its plates, which are normally held engaged by springs, and release the brake. The layshaft 3 then drives the shaft 6 through gearwheels 4, 8, of small and large diameter respectively, and the crank turns slowly to cause the ram to descend on its working stroke. At the bottom of the stroke, position b, the compressed air to the cylinder 13 is shut off and the clutch 9 restored by springs to its disengaged position, and a cylinder 14 is operated to engage the clutch 10. The drive is then through gearwheels 5, 7 of the same diameter, giving a quick return stroke to the press ram.
